In Episode 1 of The Unlocked Podcast, we start with the foundation: what DNA is, what genes do, and why gene expression is the key to understanding human performance.

Most people grow up thinking DNA is a fixed script. In reality, DNA is an instruction manual, and gene expression determines which instructions are used at any given time.

In this episode, we explain DNA in plain language, break down how genes build proteins, and connect those proteins to outcomes people care about: training results, recovery, stress tolerance, mood, and cognition. We also introduce epigenetics, the science of how your environment can influence gene activity without changing your DNA sequence.

To give you context for why this matters now, we walk through major milestones in genetics, from the discovery of the double helix to th ...
